The first gear 26 and the second gear 27 are adapted to each other. A push switch is provided on the magnetic separation frame 14, and the push switch is used to turn off the electromagnet on the magnetic separation frame 14. A trigger rod is fixedly installed on the inner wall of the magnetic separation box 1. The rotating tube 3 will reciprocate up and down when it rotates. A guide tube is fixedly installed on the top wall of the magnetic separation box 1. The rotating tube 3 rotates through the top wall of the magnetic separation box 1 and extends into the guide tube. A transmission frame 5 is fixedly installed on the rotating tube 3, and a transmission groove 6 is opened on the inner wall of the guide tube, and the transmission frame 5 is slidably installed in the transmission groove 6.

[0033] A motor for driving the rotating tube 3 to rotate is arranged above the guide tube, and a telescopic rod is connected between the output shaft of the motor and the rotating tube 3 (to adapt to the lifting and lowering of the rotating tube 3). The rotating tube 3 will drive the transmission frame 5 to rotate during its rotation, and the transmission frame 5 will slide in the transmission groove 6 during its rotation, and the transmission groove 6 is wavy, so that the transmission frame 5 can move up and down, and the transmission frame 5 drives the rotating tube 3 to move up and down.

[0034] When the rotating tube 3 moves downward, the magnetic separation frame 14 moves downward to turn over the waste, and the electromagnet on the magnetic separation frame 14 is used to magnetically separate other metals in the waste copper. The electromagnet attracts other metals to separate the waste copper from other metals; when the rotating tube 3 moves upward, the guide plates 13 are close to each other to block the box opening of the recycling box 2, and the trigger rod squeezes the pressure switch.

A recovery rack 15 is fixedly mounted on the side wall of the recovery box 2, and a recovery groove 16 is provided on the recovery rack 15.

[0037] When the rotating tube 3 moves upward, the first piston rod 9 moves upward, and the air in the top of the first piston tube 8 enters the second piston tube 10 through the connecting tube 12, so that the second piston rod 11 moves into the second piston tube 10, and the guide plate 13 moves into the recovery box 2; conversely, when the rotating tube 3 moves downward, the first piston rod 9 moves downward, and the top of the first piston tube 8 absorbs the air in the second piston tube 10 through the connecting tube 12, so that the second piston rod 11 moves to the outside of the second piston tube 10, and the guide plate 13 moves to the outside of the recovery box 2.

[0038] A pressing plate 20 is slidably installed in the pressing box 19, a pressing rod 21 is provided between the pressing plate 20 and the transmission plate 4, a plurality of discharge pipes 24 are provided on the top of the furnace body 23, a discharge pipe 18 is provided at the bottom of the recovery box 2, the discharge pipe 18 is connected to the pressing box 19, a discharge port 17 is provided at the bottom of the recovery box 2, the discharge port 17 is connected to the discharge pipe 18.

The pressed copper block is taken out by opening the box door 22. When the transmission plate 4 moves downward, the pressing plate 20 will be driven downward to extrude the screened copper material.

[0040] A method for controlling the operation of a scrap copper high-efficiency and energy-saving smelting furnace comprises the following steps:

[0042] S2: The rotating tube 3 rotates and drives the magnetic separation frame 14 to rotate. The magnetic separation frame 14 rotates by itself to turn over and magnetically separate the waste. When the rotating tube 3 moves upward, the guide plates 13 move closer to each other to block the opening of the recovery box 2. The electromagnet loses its magnetic force and the selected waste falls on the guide plates 13 and enters the recovery tank 16.

[0043] S3: The screened copper material enters the pressing box 19 through the discharge pipe 18. When the transmission plate 4 moves downward, it drives the pressing plate 20 to move downward to squeeze the screened copper material;

[0044] S4: Put the pressed copper material into the furnace body 23 , and use a plurality of feeding pipes 24 in the furnace body 23 to add deoxidizer, covering agent and refiner into the furnace body 23 .
